Architecture Reorg

[bvelitchkine]

Both Gauvain and I are dissatisfied with the current project's architecture. It's become messy, both in the front and in the back.

Background

There should be a clear separation between: services, resolvers/controllers, providers and repositories in the background. This was the topic of a meeting.

Front-end

There's room for improvement especially in the Form.tsx file that has become very long and messy. Some key action points:

• Subdivide in smaller components
• Make a better use of react hooks (useContext, useFormHook, etc.)
